Round Corners and Border-Radius in CSS3

The border-radius property is one of those CSS techniques that has been experimental for a few of the last releases of CSS.

It is now supported by the latest versions of all major browsers.

You can use it with or without adding a border to your page element.

You can use it on all or selected corners.

Use ems or pixels for the value of the radius.

Experiment.
